Official Luthiers Forum!

anyone have any ubiquitous drill press jigs pictures to share? I want to upgrade my (radial) drill press drilling operations!

I'm thinking of the table with adjustable fence/clamping

Also improvements/additions for making a luthier's friend type fixture/jig

Also any vac setup suggestions. Mine work well, but let's see what folks are doing!

Hey Terry, in the meantime, how' the inlay project coming along?

Terry, I use my drill press for a lot of functions, even drilling! Although I still like using a hand plane a lot of my thicknessing takes place using the safety planer and drill press sander, especially neck thicknessing. I use it as a spindle sanding set up, both with the large drum and with the robosander fro fine copy work. With the table router and band saw it is the most used tool in my shop.

Collin, I am about to make a couple of the sanding disk you use. From the image above, it looks like you relieve the outer edged of your disk, is this just an optical illusion, a slight arris, or an extended curve of the lip if that makes sense?

Cheers Kim

Hey Colin, How do you like the functionality of that drum? What weight paper do you use? What are the pros and cons of that type drum (Standard paper sure is a plus!)

Thanks for the pic

Hey Serge,

I'm still trying hoping to get and Adirondack top for the project (That's where I was raised...)

I may need to resort to an Englemann top I have on hand. I just wanted to make it out of woods ofund in our own back yard. Anyhow, I haven't started the inlay yet. I'll definitely keep you posted though.

Thanks Terry,

It would sure be nice to get that adi top you're hoping to get, good luck with finding it!

I'll stay tuned for that project!

Serge

Kim, yes there is a slight angle on the edges of the disk, just helps with the infeed of timber, I sand down to 1mm thick using this and you don't want thin timber hanging up on an edge. I just use two layers of 19mm ply the top one drilled right through and the bottom one just relieved for the internal nut and washers. Insert and tighten the bolt and it's nuts then glue together. Stick self adhesive velcro hooks to the bottom and your ready. I have a number of them ready made up with different grits.

Terry, I love the big bobbin sander, It's got a cam lock for changing the loading. I cut up the heavy cloth backed abrasives made for a belt sander and they give a good length of service if cleaned regularly with the rubber belt cleaner. I use 80, 120 or 180 grits according to the job.

Thanks for that Colin, I have some 6" disk made just as you have described earlier but was wondering about the reliability of the self adhesive backing on the velcro hook pads.

Do you seal your ply with anything after you level sand the bottom of the disk on the drill press table, or do you just blow them off and stick them straight to the sanded ply?

TIA

Kim

Kim, as you say, I sand the disc flat using the table, like this:



Then just wipe it clean and add the self adhesive velcro hooks, I get it in 6" wide rolls. It has never even looked as if it would come loose.

Thanks again Colin, where do you buy 6" wide rolls? The only stuff I can find locally is a pre-cut 6" disk with 6 disk of paper in 3 grades. It's called a velcro starter kit and is murderer at +$20.00 au for a kit

Cheers mate and once again TIA

Kim

I see on your bobbin sander a groove where you push and insert your cloth backed abrasives, do you also glue the abrasive to the bobbin cylinder or that groove or recess is enouh to keep the abrasive on the bobbin ?

i hope my question is well formulated here

Thanks for the great tips and TIA for this one!

Serge, the bobbin has a hole bored down it, that the abrasive is pushed into, an oval rod is pushed down and twisted to lock the abrasive in place.

Terry, I don't need to tell you that it's important to level the table precisely with a bent wire in the chuck before sanding the disc flat.

Kim, I bought the velcro from Axminster here in the UK in 1m long rolls. They only seem to have 115mm wide now.

Thank you very much Colin, i have purchased a 2" diameter sleeve from our Canadian Tire store and have a slightly less than 2" dia wood dowel that is slack a bit so your idea comes at the right time!

Thanks again Colin!

Serge

Thanks Colin, boy that stuff is hard to find in a 6" roll the 115mm is as close as I have seen in a long search.

Cheers

Kim
