  • Thin sliver of glue onto brace then clamp in place with a block either side of body
  • Leave to dry for an hour
  • Then sand top again using radius dish to level off
  • Mark brace positions as per the back, cut out with handsaw and remove keffin to 3mm depth with knife

 Neck

  • Plane one side with No. 6 plane so square and heel block is flush with neck
  • Mark shape with template onto heel
  • Cut shape with bandsaw
  • Mark centre of neck and place into dovetail jig

Week 13 – More body work

Posted on May 27, 2015December 1, 2019 by Iain 'Cutty' Carlin

More body work

  • Use edge trimmer in router to take excess of back while in mould. Trim to match the side
  • Check rotation direction of router and follow that direction round the back in mould (e.g. anti-clockwise)
  • Split mould to remove back and sides
  • Tidy up any excess with chisel or sanding and insert back into mould with back down ready to do front
  • Front the same as back – trim with block plane to get neck and base roughly the right height then sand with radius disc till you can see even deposits of wood dust round complete perimeter of body
  • Glue in kerfing as per front and hold in with pegs

 Neck

  • Plane neck block flat, use template to locate position on neck then glue and clamp in place with 2 ‘G’ clamps

Week 12 – Fitting the back

Posted on May 20, 2015December 1, 2019 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 April 29, 2015December 1, 2019 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 April 22, 2015December 1, 2019 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 April 15, 2015December 1, 2019 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 April 14, 2015December 1, 2019 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).

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 April 1, 2015December 1, 2019 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
