Week 12 – Fitting the back

Posted on by Iain 'Cutty' Carlin

Back fitting

  • Align back on sides so that centre lines up and in position
  • Taped back to sides with masking tape
  • Mark brace positions on kerfing with sharp pencil
  • Mark side location on braces with mini (10mm long) sharp pencil (broke off clutch pencil so used that)
  • Cut sides in marked location with hand saw and chisel & sharp knife to cut off kerfing to 3mm deep

Week 11 – Back kerfing

Posted on by Iain 'Cutty' Carlin

Back preparation

  • Removed sides from mould (had to use big chisel to get sides out of mould)
  • Put blocks and dowels into holes in mould to raise the back sides above top of mould
  • Use large chisel to take off material to top and bottom from waist, keeping the height at the waist
  • Use block plane to taper down till sanding dish fits on with a rock at the hips
  • Plane hips till block nearly flush
  • Sand in clockwise direction until even layer of dust is produced round the circumference of the sides

 Kerfing

  • Fit the kerfing dry and cut to size – slide into bends on sides to avoid breaking the kerfing
  • Glue and hold down with pegs (with rubber bands fitted for extra pressure)

 Neck

  • Planed neck and head together to get flush fit
  • Glued neck and head together with blocks either side and 2 “G” clamps

C# tip-bits

Posted on by Iain 'Cutty' Carlin

Learning some interesting stuff doing the edX Microsoft Programming with C# course. Thought I’d list some of them here for reference

  • The test value in a while loop is called the sentinel value.
  • A do loop always executes at least once (so use it instead of setting the sentinel value first before entering a while loop)
  • You can use named arguments so that you don’t have to pad out optional parameters, e.g.: StopService(true, serviceID: 1); serviceID is the name of one of many optional parameters but not necessarily the second one for the StopService method.

Week 10 – Blocks and Neck

Posted on by Iain 'Cutty' Carlin

Fitting neck and end blocks

  • Plane blocks so that bottom is flush with bottom of jig
  • Had to plane chamfers into sides of the neck block
  • Had to plane down the contact edges so they are flush with the top and bottom of the sides
  • Glued blocks into place and held with “G” clamps

Neck

  • Started on the neck. Thickeness to 18mm then cut to jig dimensions on band saw ready to glue (did another crap cut on the bandsaw)
  • Using scarf joint method instead of laminating (is stronger but not necessarily easier)

Infopath form error when calling WCF service via SSL

Posted on by Iain 'Cutty' Carlin

Interesting issue with a few Infopath forms. They’ve been working fine for ages using a WCF service to update another system.

When we changed our SharePoint site to use SSL, the form was generating an error when calling the WCF service. There were a number of factors at play:

  1. The WCF service was not configured correctly to have an SSL end point. By changing the binding configuration in the web.config for the web service, I was able to get the WSDL to display correctly using https when browsing to the service. However, the form still didn’t work AND the WSDL returned had the wrong URL (was the internal server name not the FQDN).

Week 9 – Moulding Sides

Posted on by Iain 'Cutty' Carlin

Moulding Sides

  • Removed 2nd Side from bender (was a bit charred due to being heated too long)
  • Same process as 1st side to put into mould:
    • Remove 1st side
    • Cut roughly to size with some overlap
    • Set centre line and mark with square
    • Cut using block and Tenon/dovetail saw
    • Place both sides into jig and tighten up block
    • Had to block plane edges to fit flush

Front braces

  • Cut thin flat braces for front from left over top and bottom materials (not enough for bridge brace so had to modify the shape to suit available materials)
  • Glued front braces, bridge and sound hole braces and placed into go-bar jig to dry

Week 8 – Side bending part 2

Posted on by Iain 'Cutty' Carlin

Second side bend

  • Same as first side (couple of notes below)
  • Make sure the waist block on bender is centred correctly to drop into the slot
  • Push down on top as you pull over the blocks – push with left hand while pulling block with right
  • MAKE SURE YOU DON”T LEAVE IT TOO LONG with the heater on – it burns the wood!!!

 First side into guitar mould

  • Put first side into the guitar jig/mould
  • Put in first then tighten up the spreader
  • Cut off excess on ends if spreader won’t fit
  • Tighten spreader and mark sides to centres and cut to centre line

 Cross brace curves

  • Carve curves into the cross brace using a chisel
  • Use thumb planes to taper sides to a point at the top
  • Sand down sided and tops

Calling lists web service fails when using SSL but works with HTTP

Posted on by Iain 'Cutty' Carlin

Had an issue where a Data Form Web Part was calling a list service (asmx or svc) on a different site collection in order to expose data between the two sites.

It would work internally (using http), but once the page was loaded externally, we would get an error. Externally the site is loaded via https.

Trying the same page internally with https generated the same error.

Turns out the https site needs to be configured as an INTERNAL URL in Alternate Access Mappings in Central Administration. We had it configured as Extranet. It is possible to configure both https and http urls on the same default zone in AAM rather than in separate zones.…

Week 7 – Side Bending

Posted on by Iain 'Cutty' Carlin

Side Bending

  • Thickness sides to 2.5mm
  • Cut to 115mm wide
  • Turn on the heating pad to warm up
  • Mark top and bottom and front with white engineers pen
  • Wet side and wrap in alfoil
  • Mark the waist position on the alfoil and insert into bender with bottom to bottom of jig
  • Put springs on clamps and side blocks after inserting wood
  • Heat for 15 minutes – screw down waist till tight then back off 2 turns
  • Pull over spring blocks to bend sides – may need to pull back and repeat
  • Turn off heater after 15 minutes and leave for a week to set bends

Top braces

  • Plane top braces to 15mm high
  • Cut leftover spruce from top to cover top of join in X-braces –  50mm long and as wide as brace
  • Glue and hold down with masking tape

Main brace hole for truss rod adjustment

  • Find centre of top main brace on front, mark 7.75mm up from botom and drill 9.5mm hole(for access to truss rod nut)
  • Chamfer other braces for top so centre is 3mm wide, remember not to go beyond the bottom width
  • Cut small 45 degree angles on ends of small braces to provide slotting into the cross braces
