CHEMI-WELD FITING METHOD

Chemically welding a Collar to your boat is an even stronger fitting method. We use the same glue that high-rise buildings are now fixing large panels of glass in with (it's stronger than bolts!).

SUITABLE BOATS

Big fibreglass boats

Medium to big fibreglass boats, with flat or clinker sides. Clinkers must contain a consistent height.

Big pressed alloy boats

Larger pressed/clinker sided boats that can handle the weight of the extra large external fixings required.

Big plate alloy boats

Plate boats have the added option of mig-welding the box-sections to the hull (must be close to 3mm thick)

Small fibreglass tenders

TENDERS under 4m that have less than 15hp outboards. No external fixings are used. Collar is glued on.

Not suitable for poly boats of any size.

HOW DOES IT WORK?

3 ESSENTIAL COMPONENTS

SUPER STRONG FIXINGS

Fixing the box-sections to the hull is done by either using chemical adhesion (T-Rex Power adhesive) or if an alloy boat, by mig-welding the box-sections directly to the hull.

BOX SECTIONS INSERTED

Box-sections are cut & the Collar routed out to hold them, so the Collars can sit flush over the top of the box-sections once fitted. The box sections go on first, then then Collar on top.

STRONG OUTSIDE SHIELD

Holding the Collar hard against the boat is a super strong length of flat bar (6mm thick x 160mm high) which is screwed to the box-sections. The tip of the screws are inside the hollow boxes.

CHEMI-WELD STEPS

1. Clean surface area

The surface of the boat is cleaned & buffed to ensure max grab of the glue.

2. Adhesive or mig-weld

The adhesive is applied as several stripes to allow for quickest dry time.

3. Attach all box-sections

All boxes placed according to their locations within the marked Collar.

4. Fit Collar & Fixings

The Collar sits snug over the top of the box sections, and the fixings hold it.

5. Apply T-Rex underneath

A long glue line is applied underneath to ensure the Collar doesn't move.

6. Finished!

Allow a full week after glue line is applied before using boat for first time.

HOW LONG UNTIL I CAN USE MY BOAT?

Adhesive applied = 2 weeks minimum

chemi-weld method.Cameron222

When using the T-Rex Power glue, allow 1 week for box section glue to dry + a further 1 week for glue under Collar to dry before using boat.

Mig-welded method = 1 week minimum

box sections welded to plate boat

When using the mig-weld system, it usually takes 1 day to fully fit the Collar. But allow 1 week for the glue line to dry before using your boat for first time.

SUPER STRONG FIXINGS

The fixings used are very strong and, due to their size, heavy. The extra weight is the biggest reason why a chemi-welded fitting may not be suitable for the average tinnie. As well as the extra costs (especially in labour) involved with this method.

Inside the 3mm box section, another 4mm plate is welded to the outer shell, so the screws anchor into 7mm of plate in total.

The heavy-duty flat bar is 6mm thick x 160mm high, & often 4m long. There's about an inch of Collar top & bottom that can be seen.

Behind each box section, hidden in the middle of the remaining foam Collar, is a 4mm thick internal plate to anchor the screw. Plates are inserted as part of kit.
