Re: Aluminum metal working

Bro are those extended spindles used for pipe working? Where can I get a Bosch angle grinder sanding pad and disc? tks

yup. i extend all my die grinders for better maneuverability and access sa blade and for safety in case mag shatter yun blade hindi inline sa hand yun blade but around 40mm further. the bosch velcro pad sanding disc i got from true value and yun pads part ng stocks ko noong available pa kyk, pero meron yata sa wilcon or ace ng velcro pads n sandpaper.

What do you think about the welding rotator? Looks easy enough to DIY one. Probably good for welding pipes.

i was thinking about making one before but i needed a way for it to have an adjustable variable speed drive mechanism, and i figured it would only be useful for straight pipes that can rotate freely, so didn't pursue it anymore, instead i practiced welding on a lot of tubing and eventually you'll get the feel of how to maintain the rhythm of moving the torch and when to add filler.. although i did invest in a nice small lightweight tig torch n gas lens set up to get a nicer weld....and of course soft leather gloves....

Re: Aluminum metal working

I had to search what a gas lens is ... here I found some info.

Re: Aluminum metal working

glass lenses should allow you to have a longer tip which is really nice for tight corners especially when making exhaust pipes....

I forgot to ask Golden about this today. Bosch is carrying SIA abrasives so I reckon they will have these backing pads and all the necessary accessories to hook up these consumables to the power tools.

From what I have understood from the EB today they also intend to widen the available range of SIA abrasives in the local market.

Re: Aluminum metal working

i asked one sales rep kanina sa Bosch eb and she said that the belt sizes can be custom made to the size needed, now i need not go to mayon for that.if panda is one of the distributor then Araneta nalang katapat ng travel ko for belt sanders. i use 4x24 inch for my makita belt sander and will be using 12 inch wide belt sander ones i get my drum sander commisioned

I wish I knew about this earlier.

This tool below has been in my list for quite sometime now. Major drawback is consumables' local availability.

The belts are 2" x 36" and are uncommon. 3M makes these.

If I could purchase SIA custom cut belts even at a minimum of 6 belts / grit per order then it will be an attractive option for me.

I'll inquire about this later. Thanks bro for the info.

You're right bro Jay, the vansant belt sander is a very nice addition indeed in a metal or wood shop, very useful indeed, plus astig din ang dating ng belt sander na yan.

But if we could fabricate a somewhat similar get up of that or the two links I posted sa "TOOL LOOT " thread regarding belt sanders, as metal workers here, siguro mas ok yun kasi hands on na DIY project yun, diba !!! :p 🙂 😉

Re: Aluminum metal working

i have an air belt sander with a 1/2 in wide belt, i had the belts made somewhere in q.c, found a place that makes custom sized belts and ordered several grits. Then i discovered that the belts have an expiration date, the glue thats used will only lasts up to 3 to 5 years depending on the brand, now i make my own belts using abrasive cloths and different types of glues that i'm experimenting on....

Re: Aluminum metal working

Butch ... bro have you ever tried Aluminum Mig Welding before?

I'm looking at this spool gun below but am having seconds thoughts on how good it will be on aluminum mig welding.

Hope we get to meet you on the next EB.

Re: Aluminum metal working

i have a 250 amp mig welder and i have all the parts for aluminum welding for it like the teflon liners, bigger tip, and nozzle, one thing i discovered, at full amps i can only weld sheet metal about 2 to 3 mm thick, any thicker and i'll have to preheat otherwise the filler would just ball up, not enough juice i suppose, unlike a tig where i can heat up the workarea using the tig before adding filler, not sure though if you use a spool gun, because newer migs designed for aluminum has a push pull wire roller mechanism and pulsed mig power supplies....

Re: Aluminum metal working

Bro ... the specs for the Millermatic 180 says that it can weld up to max 1/4" thick aluminum (which I suppose means that the machine is running at full duty cycle). Looks like it could be thinner when in actual work already.

What do you use to pre heat aluminum? Mapp Gas Torch or Oxy Ace? tks
