This forum will present the various tools used for scratchbuilding. For those who are new to scratchbuilding, this forum will strive to provide pertinent info and how-to-do it tutorials on scratchbuilding.
Contributors to this forum are welcome!
I will be posting various info on this topic soon, stay tuned.
A few assorted measuring tools from the workbench... .
Top to bottom: Combination square. General purpose tool, comes in handy to draw reference lines across your jig.
X-acto mini-square. One of my most used tools. Useful for squaring up brass motor brackets, verifying your bent wires are a true 90 degrees, marking wire and tubing for length etc.
Seamstress tape. Flexible tape works well on curved or uneven surfaces, useful for marking stripes and decal locations.
6"scale. General purpose measuring, small size is handy, can also be used as a depth gauge. Available in Inch measurement ranges as small as 1/64, reverse side features fraction/decimal equivalents. Also available in Metric. Also used as a guide for scribing lines into plastic sheets or bodies.
4' Vernier Caliper. Accurate to ~.001", general purpose for precision measurements of motors, chassis parts etc. Also acts as depth gauge. Small size is light weight and fits into your pit box easily.
Left to right: Automatic center punch. Great for marking brass sheet for drilling, frees up one hand to hold workpiece.
Large pin vise/drill chuck. Made from an old 1/4" Jacob's chuck, drilled tapped an old screwdriver handle so it would thread in. You can now buy a similar tool off the shelf, but it has a 1/4" hex drive for use in a manual driver handle or screw gun. Used for drill bits and accessories that are too large for the small pin vise. Good to hold tubing while cutting too as it doesn't crush or distort it. Holds bushings and tubing for reaming or chamfering.
1/8" to 1/2" Tapered reamer. Removed T-handle and inserted into old drilled out screwdriver handle. Reams tubing, plastic, wheels etc easily.

Bastard file. General shaping/filing of brass, steel and plastic.
1/8" counter bore. 1/8" Drill blank guides the cutter, use it to spot face and narrow 1/8" wheels, gears and axle tubes. Can also be used square up crooked/angled cuts on 1/8" tubing.
3/32" counter bore. Used in similar fashion as above for 3/32" applications.
1/8" to 1/2" step drill. By far the best tool for drilling brass and plastic. Doesn't snag, distort or tear the work, steps up in 1/32" increments, automatically chamfers and deburs holes if used carefully.
Machinists vise. Holds work square and steady for filling, drilling, shaping etc.

Clockwise starting at top: Mini-phase soldering iron temp controller, Wrightway Hakko 55W soldering iron, Inland 100W soldering iron, 60/40 solder. 55W iron is good for most soldering. 100W iron is needed when soldering .062" brass or .093" piano wire.
"Edsyn" fan (blue), "Stay-Clean" acid flux. Highly recommend using Stay-Clean brand rather than other brands. Fan reduces "lead" and acid flux fumes.
Call me old fashioned, but I still like using an Unger/Weller soldering iron, even though I've worn out a few tips/handles. The current tip is 45 watts made for stained glass work. Heat is controlled by an old Dremel speed controller. Really like using Radio Shack Silver Bearing solder as it stays real shinny. Acid flux from the track, and a 20 year old tin of NoCorrode. Stand is from Radio Shack too...
They say you can never have too many clamps Clothes pin come in handy as you can trim the tips to suit your needs, and they are real cheap. To hold small parts for painting I put together some Alligator clips glued to skewer sticks. The small bar clamp is from HF, and have used the S out of it since I got it home.
What's a schrach builder without a jig? This is an old one a friend made out of Aluminum. Built a bunch of cars including all my current hardbodys with it. With no front axle holes 1/2" x .032 brass strip serves fairly well as wheelbase jigs.

Keith Tanaka: Low turnout for today's Nats races. Hope to see more racers tomorrow at BPR for the "Mixed" race and GTP/Mid-Engine races, A lot of very good raffle prizes (model kits) for those who race tomorrow at the Nats. Also, get your t-shirt.

Keith Tanaka: So, for those who ordered a t-shirt(s), you'll get two t-shirts for the price of one!!!! Actually, the screen printed t-shirts are not bad, but just not as good as the digital printed ones.
Oct 18, 2019 19:34:39 GMT -8
Keith Tanaka: Good news, bad news. The bad news, I received the t-shirts but they were incorrectly "screen printed" which is a lower resolution than "digital printing". The good news, vendor agreed to send me "digital printed" t-shirts at no cost.
